,This invention relates to talki machiries and has reference particularl to t e manner nwlnch the sound boxes 0 such machines are connected to the sound-conveying andengu fing-devices thereof.

.is well known, record-tahlets for the,

mechanical're roduct'ion of recorded sounds, I disk or other form, are of two t es depending .on. the character of the und ations. of the record-groove, these be termed the vertically undulating and the aterally undulating types. For reproduc' sounds'from these two types of record-ta lets, machinesdifiering 1n constructionhave heretofore been re uired, so that a 'but one mac one oft'hese two types. he obiect of my invention is to provide a talkingmmhine so constructed that it may 'he to-neproduce soundsfrom either of of records differing in the character o the sound-undulations of the record-groove. ,This' is accottiplished by providing a sound-box which is arrangedto sume either .of twooperative'positions, in one will 00 operate with a record of the verticall undulating-t e to reproduce the recorde "sounds witha record of the laterally undulating type. Thus, the sound-conv'e .device- 0 talking-machine, CODSlSlEIDg of i-hornl 'alone orflaeconibined horn and rmitting -movement o the sound-box -to e'1therof its twopositions. r y r In the preferred embodiment of the inventionf'a tone armiisemplo ed and a joint is provided near the free en the ounfl box maybe Wed from one operative osition to a second in which its dia hragmis d angle'to the the box is in either -an-amthe first position.

For the purpose of such pivotal mounting, the, tone-arm is' here shown as having a yoke 2 secured thereto in which 'is pivoted a cross-heed carrvi a sleeve 3 adapted to receive vertically 'isposed-pin The other end oft-ho tone-arm carries the sound-box, 4'-havin a stylus-lever 5 in which is secured a stylus 6. The lever 5 is pivotally mounted on the wall'of the box hy havi v notched lugs thereon in which 'are receiva cured tothe box. its end and bears on Member] is 'bent' over at end ofjthe lever yieldingly agai 'ist' the'dia phragin $of the box. At .its.:o ut cr e' d, the toncfaxin' tits bent, preferably in the 1 manner shown, to form a portion 9 thei'ein tl e axis pf which is inclined to the akis of the inain'port'ion off the tone a'rrn. The portion .9 is adapt'cd'to receive a tuhuiar le'xtension 1 O"o'n' the, soundbox 4', this extension being coniiectetLto the sound-box bya short fubular picc'e 1'1 and having its: axis s ubstantiallyparallel to the diaphragm 8.

If desired,the slot 12 may be so ormed'that it extends in the direction of the slength of ,tube as well as around the ,5 same so that the turning movement of the sound-box will cause tube 10 to move into ,"and out of tube- 9; such relative movement oftubes 9 and '10 may be desirable to coinensatefor the use ofstyluses of different ne-arm andin these figures 14 indicates a disk sound-record having a record-groove of.

the laterally undulating type, ,While 15 indicates a similar record having a groove of the verticall y undulating type. in Fig. 1, itwill be-seen that the diaphragm of the sound-brushes in a plane substantially parallel to the axis of the tone-arm in a position with lateral undulations .in the record-tablet 80 14;; in Fig.2, however,-the diaphragm .ex-

" tends across the axis'of the tone-arm and is somewhatinclined' so that it will be vibrated by the ooaction of its stylus with vertical undulations.

- The movement of the sound-box about the pivotal. connection thereofto the tone-arm carries the box to either of, two operative po-.

sitions, and in bothl-of these positions the single st. lus of. the sound-box rejects-from facter of the sound undulations, as vertical or lateral, these disks being mounted upon the same support as the turn-table of -the.ma-

chine,

Having now-described my invention, what Iclaimas newtherein and desire to secure by Letters Patent. is as follows 1. In a talking machine,;'a sound-box having a "diaphragm and a tubular connection thereto for :ca, ing sound, said connect on {having a joint tgerein permitting movement -9f-thesound-box to either of two operative 'ositions, als' in le stylus being adapted to rate the diara n in either of sa id.pos1- tions and sai sty us pro'ectiri in substan j tially thesame direction rom t re sound box in both of said ength's in the two positions of-the sound-.

' o'sitmns" of the sound-box relatively to the the-box m the same direction, t atis, downwardly in the structure shown the drawmgs; -therefore,- a talking maclune equipped tiall I i Tris-specification signed and witnessed positions, substantially'as set forth.

2. In a talking-machine, a sound convey- I ing tube, and a sound-box plivotaliymounted thereon and provided wit, a sin le stylus, said box being movable about t e pivotal axis through ninetj degrees to car it 'to' either of two-o erative positions in oth of which said sty us rojects in substantially the same direction rom thesound-box', substantially asset forth. I

3. In a talking-machine, a'sOund-conireying tube and a sound-box having adiahragm mounted on said tube'and movable mm a position'in which the diaphragm is parallel to'the axis of the tube to a position,

in which the dia hragm extends across said axis, substantia y as set forth.

4. In a 'talkingqnachirig-a sound-pom; eyingtube ,a soundbox' having a single stylus, and two telescopingtubular pieces,I-one on said tube and the other-on said box, ermitting movement of the sound-box-re' atiyely 'to the tube to either of two 0 erativei,po s1.

tions in both of which said sty usproje'cts in substantially the same directiorrfrom the sound-box, substantially as set forth.

to be vibrated-by the coaction of the stylus 3 5. In a talkin -machine, 'asound-conveying tube, a sounc -box having a single stylus, two telescoping tubular pieces, one on said tube and the other on said box, permitting and a pin 'on oneof said ieees enteringa slot in the other, substantia y as setforth.

6. In a talking-machine, a sound-conveying tube having a tubular portion at its end turned at an acute an le to the axis of. the

tube, and a sound-box aving a stylus pivotally mounted on said-portion and adapted to y be turned about the same to'eitherof two 0 erative positions, substantially; asset-fort f7. -In--a talking-machine, a sound-conveying tube 'havinga tubular portion at its end turned at an angle to the axis of the tube, and a sound-boxhaving a stylus and a tubular piecefixed to the box and; telescoping with 'said ortion to permit turning the sound-box relatively to said tube to either of two opera;

' tive pos tions, in both of which the stylus of the sound-box rojects in substantially 'the same direction rom the sound-box, substar 1' as set forth.
